Crackling sound Mine crackles continuously. Changing the settings doesn't make a difference. It's like a rapid fire click-click-click. I cleaned the ceramic plate, but it made no difference. What causes that crackling?

You need to look inside (through the front grill) with the lights turned off, and try to spot the sparking/arcing high-voltage - - what you're likely hearing is a spark where high-voltage is grounding-out due to a fault in the wire insulation or some other insulating structure.

Once you isolate where in the machine it's arcing, you may be able to determine where it is and whether or not it's within your skills to fix it. If it's an XL-15 as indicated by this category, it's no longer in warranty (no longer even supported by the manufacturer, for that matter, so it will be up to you to determine how much you want to work with high-voltage electricity.

If you can find the spark, you might be able to report back here for more detailed advice. Hope this helps.

To stop the crackling sound, you need to remove all of the dust particles from the wire in the back. Sometimes when the unit is extremely dirty you can see sparks emanating from the wire, this is what causes the crackling sound. The unit has a built in cleaner you can lift up and down to perform this task, located on the top, but this doesn't work extremely well.

I usually take a can of compressed air and blow as much of the dust I can off the wire and all surrounding internal areas as I can. To do this, approach the unit from the front, and turn the blade door slightly so the wire can be seen. This along with a thorough cleaning of the blades should eliminate the crackling noise. Of course, make sure the device is unplugged before performing any cleaning.

Mine does it too, I finally just tried something else when I was cleaning the blades. I took some alcohol on a qtip and with the blades out of the machine I wiped up and down the line wires that are inside that go from the top to the bottom, and also the little balls that are on the bottom of the wires that slide when you turn your unit upside down. It seems to work, I do it every time I clean the blades. scribner062

Have you cleaned the unit good and made sure that there is nothing crossing the grid wires? It sounds as if it is cutting off and resetting for some reason. Mine runs continuously. I take an air compressor and blow mine out every time I clean it. Also, on some models, you have to hold the on button down for several seconds to reset it after cleaning. Hope this helps.

Not sure about the smell though. Mine has started to smell a little strange and
I haven't figured out how to fix that problem.

I had the same problem with mine, it would start then go into drying mode. I got it to work properly by smacking it around for about a week then it went back to it's lil tricks with drying mode again. After trying just about everything short of using it for target pratice, I made sure it was clean and dry then I turned it to the Medium setting, pressed the power button waited just a second for the fan to go into the meduim fan level, then I pressed the power button again holding it in before it went into the drying cycle, while I held the button, (don't release) I wadded up some tape to keep the button depressed then I put some tape over that to keep it that way. It works perfect! Note, mine never had any crackling issues to begin with, just the drying cycle thing so use this suggestion at your own risk. Good luck!

there's usually a troubleshooting guide stuck on the inside of the door. it suggests a systematic flowchart for diagnosing the problem.
you should be able to isolate it to either the power supply (means replacement), or one of the cells.
on mine, one of the many little vanes got a bent during cleaning, and was shorting out. (it doesn't take much.) a quick visual and very little judiciously applied force straightened it out and fixed the problem.
i've also found that the unit will crackle a lot after a cleaning because of drops of water remaining in the cells, so i usually reassemble everything, but leave the unit turned off for an hour or two, which lets the blower on the furnace dry the cells for me.
